However, Wilson's wardrobe malfunction was not what it seemed, revealing a fake double nipple instead of her own breast.

The Pitch Perfect star teased the gag during one of her monologues, where she told the audience: "There’s been a lot of jokes tonight, many of them brilliant because I write them,” she said, before deciding to turn the evening into a serious matter.

"Thinking negatively about your body is nothing positive. I was born with a slight deformity. I have learned to love myself, and I want to say to everyone out there that no matter what size or shape you are, just love yourself."

At this point, her glitzy purple dress slipped down to reveal her two fake nipples, with Rebel adding: "Thank you guys. I don’t know why some of you are laughing though, because this is a really serious bit."

You can catch all the action from the Rebel Wilson-hosted MTV Movie Awards when it hits MTV UK on April 15 @ 21:00!
